Mid-Shift Status: Mon EVE

H1 just had a lockloss (after 10.5hr lock) due to a big wind gust (coincident with an audible "creak" in the Control Room).  Prior to this, coincident with the beginning of this current wind storm about 3.5hrs ago, the Squeezer unlocked taking us out of Observe (similar to last night when wind storm occurred).  Naoki & Vicky spent a bit of time trying to get the squeezer back, but I overheard them talking about lots of motion on SQZ optics).  

Was getting ready to transition H1 to a No Squeezing state for the night, but the Squeezer locked back up (see Naoki/Rahul alog). But it only lasted 30min until winds increased.

Here we are after the H1 lockloss.  By default, will see if Squeezing is possible, but if we run into the same issues & it's windy, will transition H1 for No-Squeezing operations for the night.
